Hello Stefan and others,
this series adds support for booting Marvell platforms via UART (those bootable with kwboot) at higher baudrates.
Tested on Turris Omnia up to 5.15 MBd, which is 44x faster than 115200 Bd.
The user can direct kwboot to use higher baudrate via the -B option. (BTW this option was there before but did not work with the -b option.)
Only the payload part of the KWB image is uploaded at this higher baudrate. The header part is still uploaded at 115200 Bd, since the code that changes baudrate is injected into header as a binary extension. (The payload part makes up majority of the binary, though. On Turris Omnia the payload currently makes ~87%.)
The series also contains various other fixes, refactors and improvements of the code, upon which the main change is done.
